In other words, the crystalline alloys were characterized by brittle fracture and abrasive wear, while the amorphous counterparts were characterized by severe plastic deformation and flowing. 非晶合金的磨损机制主要为塑性流变,晶态合金的磨损机制主要为脆性断裂以及磨粒磨损。
Crystalline fining grain can restrain the cleavage fracture. 细化晶粒可抑制脆性断裂。
In this paper, we have concentrated on the behavior of crystal dislocations near crack& tip during the initiation of crystalline solid fracture starting from the fundamental principles of rheological mechanics. 在本文,我们从流变力学基本原理出发,着重探讨了晶态固体起裂时裂纹尖端附近晶体位错行为。
The concept, formation conditions and formation mechanism of metal matrix intragranular composites were presented. The intragranular composite between α-Al and TiC leads to crystalline fracture. 提出了金属内晶型复合材料的概念、形成条件及其形成机理,分析了其发生穿晶断裂的主要原因是由于TiC与α&Al之间发生内晶型复合。
Influence of Crystalline Structure on Fracture Strength of Diamond Films 晶体结构对金刚石膜断裂强度的影响
It was seen from SEM micrographs that there were spherulites, rod crystalline and amorphous continuous phase on the fracture surface of PUU. The sizes and the distributions of the crystallines depended on the changes of the hard segment content and the soft segment molecular weight. 从SEM照片上看到;在PUU的断面上存在着球晶、棒晶和无定形的连续相,晶体的尺寸和分布依赖于硬段含量和软段分子量的变化。
The difference between the microstructure of amorphous and crystalline materials, which caused the difference in fatigue life, was analyzed and the fracture processes was characterized in view of mechanical properties. 分析了非晶合金与晶态合金在疲劳寿命上的不同是因其显微结构上的差异所致,并从力学性能方面分析了其破坏机理。
Aperture Couplings of Waveguide The reservoir spaces of the Doushantuo Formation consist of inter crystalline pores and fracture voids. 陡山沱组的储集空间有晶间孔隙和裂隙缝洞空间。
Dimensions of the stress and crystalline have influence on cleavage fracture. 应力的大小和晶粒的尺寸影响解理断裂。
Crystalline behavior of segmented polyester polyurethaneurea ( PUU) elastomers at different annealing conditions was studied by wide-angle X-ray diffraction ( WAXD), and crystalline morphologies of the fracture surface of these materials were investigated by scanning electron microscopy ( SEM). 用宽角X-ray衍射(WAXD)研究了嵌段聚酯脲氨酯(PUU)弹性体在不同退火条件下的结晶行为,用扫描电子显微镜(SEM)研究了这些材料断面上的结晶形态。
As the crystalline limestone and the fracture of axis of fold lines grows in different degree, surface water varies, the collapse develop uneven. 由于灰岩结晶类型、褶皱线轴部裂隙发育程度不同和地表水系等多种原因又造成了研究区塌陷发育的不均性。
